Title: Fluidized bed heating furnace
Inventor: HATTORI MASAO
IPC: F27B15/18
Filed: 1989-06-14
Abstract: PURPOSE:To heat-treat a metallic material in a nonoxidation atmosphere and to maintain a specified temp. and fluid state by using a natural gas for a fluidizing gas and providing means for causing partial combustion and regulating the temp. and pressure of a fluidized bed. CONSTITUTION:The natural gas and air from tanks 12, 11 are mixed at a prescribed ratio and are sent via a fluidizing gas control valve 2 to a dispersion chamber 922 where the gaseous mixture is ejected from ejection holes 921 of a dispersion plate 92 to fluidize the fluidized bed 94 and to cause the partial combustion thereof. The above mentioned fluidizing gas is partly fed via a pipe 15 into a radiant tube 3 where the gas is partially burnt to heat the fluidized bed 94. The exhaust gas thereof is sent via an exhaust gas control valve 4 to the dispersion chamber 922. The temp. of the fluidizing gas in the fluidized bed 94 is kept detected at all times and the flow rate of the gas is regulated via a fluidizing gas control valve. The pressure of the fluidizing gas in the dispersion chamber 922 is kept detected at all times by a sensor 45 and is kept at a prescribed pressure via the exhaust gas control valve 4. The generation of oxide scale on the surface of the steel product 88 is prevented in this way and the fluidized bed 94 is maintained in the optimum state.

Title: Grass tray and manufacture thereof
Inventor: OBARA MASAHIKO
IPC: B65D1/09
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a grass tray and a method for manufacturing it wherein natural environments such as mountains and forests can be protected while pollution may not occur in disposal, an applicable range as a product is wide and the tray can be inexpensively manufactured by utilizing fibrous vegetable pieces and compression-molding them into a sheet. SOLUTION: Dairy farm grass such as, for example, grass having fiber other than wood is used, wherein the dairy farm grass is cut into a predetermined size, crushed into powder and kneaded, and this kneaded material is stretched by a press and shaped into a predetermined form, so that a product corresponding to a paper product can be shaped without using pulp as a raw material as conventionally. Thus natural environments can be protected while the product can be inexpensively manufactured. In addition, since starch is produced on a surface of a molding during a press molding process, the product surface becomes glossy thereby improving quality as a product.

Title: Manufacture of fluorescent lamp
Inventor: HAGIWARA MAKI
IPC: H01J9/22
Filed: 1981-09-28
Abstract: PURPOSE:To make a high temperature firing process needless by heating with a relatively low temperature not less than 300 deg.C after application and drying of the paints having a polyethyleneoxide as binder when forming the initial first layer for a glass tube. CONSTITUTION:As a polyethyleneoxide to be used as binder of paints for the first layer decomposes at a relatively low temperature, most of the polythyleneoxide is decomposed and volatilized, when a glass tube is heated at a relatively low temperature not less than 300 deg.C i.e. at the temperature near 324-363 deg.C which is the average decomposition temperature of the polyethyleneoxide, in a heating treatment after the application of paints to the first layer and drying. Thereby, owing to the low heating temperature the polyethyleneoxide is not wholly lost by burning and oxidation and some undecomposed substances remain while being colored but with no bad influence upon the application of paints to the second layer such as a poor appearance and the like.
